Application filed March 4, 1911. Serial No. 642,212.

To all whom it may concern;

Be it known that I, FRED EUonNaBprorrr, a citizen of the United States,res ding at Philadelphia, in the county ,of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inMechanical Movements, of which the following is a specification,reference being had therein to the accompanying drawing,

My invention relates to mechanical movements and more particularly tothat class thereof wherein a constant rotary motion may be convertedinto an intermittent reciprocating motion. In the form illustrated anddescribed it is shown as applied to a keyboard mechanism, Such forinstance as is employed in linotype machines to govern the release ofthe matrices from the ma gazine. Obviously, however, it may be used invarious wa s and in ditlerent embodiments, and I 0 not desire to limitmyself to any specific form except in so far as such limitations arespecified in the claims.

In some respects the mechanism herein embodied is of substantially thesame charactor in construction and mode of operation as those presentedfor instance in United States Letters Patent to Ottmar Morgenthaler, No.531,266, dated December 18, 1894, and Philip I. Dodge, No. 530,931,dated December 18, 1894. In these patents are disclosed escapementactuating means, wherein the rods or bails are operated by levers whichin turn are provided with cams journaled thereon. Each cam is arrangedso that upon the release of the operating lever it is brought intoengagement with a constantly driven roll in such manner that it causes acomplete rotation of the cam. This action efi'ects the two-fold result;first, of reciprocating the rod or bail so as to actuate theescape-ment, and second, by reason of the shape of the cam, of pesteringthe connected lever to its normal position. In the present instance,instead of such a cam, I employ a gear or driven member which is alsonormally held out of engagement with the roll or driving member. Thedriven member is not directly connected to an operating lever, as in theprevious instance, but is mounted so as to be capable of motion to andfrom the driving member, it being normally held out of engagementtherewith by a separate and independent device upon which it rests inits inoperative position. Specifically, the

n rma ct. etween t e Q di s e e and the driven member is secured by ancecentrically located part on the latter, which in inoperative anddisengaged position rests on the former. When the holding device istripped in the manner subsequently to be described, the driven memberengages with the driving roll and is thereby rotated, and during itsmovement the eccentrically located part contacts with another portion ofthe holding device in such manner as to restore it to its originalposition and thus to leave it in readiness to rengage and hold thedriven member when the latter comes to rest.

Referring to the drawings: Figure 1 is a transverse vertical sectionthrough the keyboard of a linotype machine, having my invention appliedthereto; Fig. 2 is a sectional front view of a part of the same; Figs.3, 4 and 5 are detail views of the principal parts of the mechanicalmovement, showlng them in successive operative positions; and Figs. 6and 7 are detail constructional views.

As is usual in linotype machines, the matrices A are stored in themagazine M and their release therefrom is governed by an escapement B,all in the manner well understood in the art. Each escapement isoperated by a reciprocated rod or bail I, the exact connection of whichto the escapement is immaterial and constitutes no part of the presentinvention. As is also customary, the machine is provided with a keyboardhaving a series of keys 0, whereby. the respective matrices areselected, their delivery being automatically efi'ected through thespecific means now to he described. Each key 0 is held in its upward ornormal position by a spring I) and is connected by a link E to a pivoteddog or pawl F, which sustains the escapement-rod operating parts innormal or inoperative position. The dog or pawl F is provide with twovoperative faces or notches 11 and 12, and its throw is limited by theengagement of a projecting pin G (shown in dotted lines in Fig. l) withthe urved slot H (see Fig. 7).

Power is transmitted to the respectively selected rod-operating parts bya constantly actuated roll or driving member 2, located in the keyboardmechanism in position to engage and actuate the driven members of theescapen ent operating devices. This rotational movement of the drivingmember 2 may be imparted to it in any desired manne as f ns-tam by th beP ll .J-

Patented Oct. 7,1913. 5

Each of the rods or bails I is connected to a driven member or gear 3 bya stud 6 lo' cated eccentrically thereon, and in such manner that whenthe gear is caused to rotate, the rod will be reciprocated to operatethe corresponding escapement. located in a bank or series over thedriving member 2 and are separated from each other by a correspondingseries of supporting and guiding plates K (see Fig. 7). Each of thegears 3 is formed with a projecting hub or boss 4 (see Fig. 6) which inassembled position occupies the vertically elongated slot 5 in the plateK. The effect of this ar-.

rangenient is to permit not only the rotation of the gear 3 but also alimited radial motion toward and from the driving member 2.

Normally the gear 3 is in its uppermost or inoperative position, asshown in Fig. 1, that is to say, with its hub 4 in the upper portion ofthe vertical slot 5. This relation of the parts is maintained by meansof the separate and independent holding device 7 which is pivotallymounted on the plate K. In the torm'shown, the holding device isprovided with two extending branches, an upper arm 8, and a lower. arm9. The lower arm 9 normally rests in the upper notch 11 of the pivoteddog or pawl F previously referredto, and in this position it supportsthe gear 3 by reason of the engagement therewith of the eccentricallylocated part 6.

gages under the upper arm 8 of the holding device 7, thus raislng thelatter above its normal position. These relations of the parts are shownin Fig. 4:. When the arm 9 has been thus removed from the notch 12 ofthe dog F, the spring D previously referred to restores the dog to itsnormal position, and as the further rotation of the gear 3 carries theeccentrically located part beyond and out of contact with the upper arm8, the arm 9 will now descend and again rest in the upper notch 11. Trotation of the gear 3 still proceeds and be eccentri-' cally locatedpart 6 again contacts with the angular arranged upper surface of the arm9, the effect of which rotation'and contact is to withdraw the gear 3from engagementwith the driving member 2. This position of the parts isshown in Fig. 5. The rotation of the gear continues until the drivingThe gears 3 are tion, as for instance by holding the connected'key down,the gear 3 will be permitted to engage constantly with the drivingmember 2, thus resulting in an uninterrupted operation of the escapementor other connected art.

Obviously many variations and changes may be made in the embodiment ofmyinvention without departing from its scope or spirit, and these willsuggest themselves to those skilled in the art. Its advantages arenumerous and well defined. There can vbe noslipping between the parts,as in the case of cams, and consequently greater regw larity of actionresults. The mechanism is self-contained, admits of assemblage withoutscrews or rivets, and may be readily placed in operative position withinthe keyboard frame-worln'orin a similar manner connect ed to any kind ofoperating or operated mechanism that may be desired or employed. Theparts may be cheaply and rapidly manufactured, as they may be madeentirely by punches and dies, and preferably from sheetsteel that may beeffectively case-hardened so as to make them almost entirely proofagainst wear. It is also so compact that a single bank or row of theassembled mechanisms will suffice for a standard keyboard.
